Nā hopena o COD, amonia nitrogen, total phosphorus a me ka nui o ka nitrogen i ka maikaʻi o ka wai

ʻO COD, ammonia nitrogen, total phosphorus a me ka huina nitrogen he mau hōʻailona hoʻohaumia nui ma nā kino wai.Hiki ke nānā ʻia ko lākou hopena i ka maikaʻi o ka wai mai nā ʻano he nui.
ʻO ka mea mua, ʻo COD kahi hōʻailona o ka ʻike o ka mea organik i loko o ka wai, hiki ke hōʻike i ka haumia o nā mea organik i loko o ke kino wai.ʻO nā kino wai me ka nui o ka COD e loaʻa i ka turbidity kiʻekiʻe a me ka waihoʻoluʻu, a hiki ke hoʻohua i ka bacteria, e hopena i ka pōkole o ke ola wai.Eia kekahi, ʻo ka nui o ka COD e hoʻopau i ka oxygen i hoʻoheheʻe ʻia i loko o ka wai, e alakaʻi ana i ka hypoxia a i ʻole ka suffocation i loko o ke kino wai, e hōʻeha ai i ke ola wai.
ʻO ka lua, ʻo ka amonia nitrogen kekahi o nā meaʻai koʻikoʻi i ka wai, akā inā kiʻekiʻe loa ka neʻe ʻana o ka amonia nitrogen, e alakaʻi ia i ka eutrophication o ke kino wai a hoʻoikaika i ka hoʻokumu ʻana o nā pua algae.ʻAʻole wale ka pua o ka algae e hoʻohaumia i ka wai, akā e ʻai pū kekahi i ka nui o ka oxygen dissolved, e alakaʻi ana i ka hypoxia i ka wai.I nā hihia koʻikoʻi, hiki ke make i ka nui o nā iʻa.Eia kekahi, e hoʻoulu ʻia nā mea ʻala maikaʻi ʻole i ka nui o ka ammonia nitrogen, kahi e loaʻa ai nā hopena ʻino i ke kaiapuni a me ke ola o nā kamaʻāina.
ʻO ke kolu, ʻo ka nui o ka phosphorus he mea kanu meaʻai nui, akā ʻo ka nui o ka nui o ka phosphorus e hoʻoikaika i ka ulu ʻana o nā algae a me nā mea kanu wai ʻē aʻe, e alakaʻi ana i ka eutrophication o nā kino wai a me ka ulu ʻana o nā pua algal.ʻAʻole wale ka ulu ʻana o ka Algal i ka wai a me ka pilau, akā e ʻai pū i ka nui o ka oxygen i hoʻoheheʻe ʻia a pili i ka hiki ke hoʻomaʻemaʻe ponoʻī i ka wai.Eia kekahi, hiki i kekahi mau algae e like me cyanobacteria ke hana i nā mea ʻawaʻawa, e hōʻeha ai i ke kaiapuni a me nā kaiaola.
ʻO ka mea hope loa, ua haku ʻia ka nui o ka naikokene me ka amonia nitrogen, nitrate nitrogen a me organic nitrogen, a he hōʻailona koʻikoʻi ia e hōʻike ana i ke kiʻekiʻe o ka haumia meaʻai i loko o ka wai.ʻAʻole ʻo ka nui o ka nui o ka nitrogen e hāpai i ka eutrophication o nā kino wai a me ka hoʻokumu ʻana o nā pua algal, akā e hōʻemi hoʻi i ka ʻike ʻia o nā kino wai a keʻakeʻa i ka ulu ʻana o nā mea ola wai.Eia kekahi, ʻo ka nui o ka nui o ka nitrogen e hoʻopilikia i ka ʻono a me ka ʻono o ke kino wai, e pili ana i ka inu a me ke ola o nā kamaʻāina.
I ka hōʻuluʻulu ʻana, ʻo COD, ammonia nitrogen, total phosphorus a me ka nui o ka nitrogen he mau hōʻailona koʻikoʻi e pili ana i ka maikaʻi o ka wai, a ʻo kā lākou kiʻekiʻe kiʻekiʻe e loaʻa i kahi hopena maikaʻi ʻole i ka kaiaola wai a me ke olakino.No laila, i ke ola o kēlā me kēia lā a me ka hana ʻana, pono mākou e hoʻoikaika i ka nānā ʻana a me ka hoʻokele ʻana i ka maikaʻi o ka wai, e hana i nā hana kūpono e hōʻemi i ka hoʻohemo ʻana o ka wai, a pale i nā kumu wai a me nā kaiaola.
